The Screen Actors Guild Awards aren't nearly as glitzy as the Golden Globes or as A-list as the Oscars, but there are plenty of opportunities to get up-close looks at potential Academy Award winners, along with up-and-coming stars and seasoned veterans on the red carpet.

The stars want to look tasteful but not too overdressed at the ceremony, in which actors pick their favorites in film and television. The styles at this year's ceremony at the Shrine Auditorium in Los Angeles were relatively understated, although there was no lack of jewels — in several cases, stars wore more than $1 million in baubles.

Among the best and worst dressed:

Now this is how a star couple dresses. Sofia Vegara chose a custom Vera Wang gown that accentuated her curves, and the fuchsia shade is guaranteed to look good in photographs. Vergara's new husband, Joe Manganiello , provided the perfect accessory in a fitted tux.

Idris Elba, the evening's only double winner, would look great in anything, although his three-piece tuxedo resembled a business suit and wasn't quite right for the occasion.

Helen Mirren was one of the sexiest stars of the evening in a Jenny Packham gown.

Rachel McAdams' embroidered Elie Saab gown with a full skirt was one of the loveliest on the red carpet. She also wore $1 million of Harry Kotlar diamond earrings and rings and a Le Vian diamond ring.

We weren't overwhelmed with Brie Larson's powder blue Versace gown, which looks like it got torn at the cleaners, but we were dazzled by the more than $1 million worth of Tiffany diamonds she wore, including a bracelet from the 2016 Tiffany Blue Book collection.

Claire Danes is right on trend with a colorblock Stella McCartney gown, accessorized with a Schlumberger lapis and diamond bracelet, diamond earrings, and Schlumberger sapphire and diamond rings from Tiffany & Co.

Nicole Kidman returned to the red carpet in a pale pink and purple Gucci gown that is a little Bohemian for our tastes.

Laverne Cox stood out in a Prabal Gurung hand-draped asymmetrical chiffon gown with a high slit and trailing sash in a striking Bordeaux shade.
